To perform a colorimetric test using the MACHEREY-NAGEL visocolor ECO Chlorine Dioxide Test Kit, please follow the instructions provided in the user manual:

1. Pour a 5 mL water sample into both of the measuring glasses using the plastic syringe. Place one of them in position A in the comparator. Only add the reagent to measuring glass B.

2. Fill the second measuring glass with 2 drops of ClO2-1.

3. Seal the glass and mix.

4. Open the glass after 2 minutes and add 3 drops of ClO2-2, seal the glass, and mix.

5. Add 3 drops of ClO2-3, seal the glass, and mix.

6. Open the glass once again and place it on position B in the comparator.

7. Slide the comparator until the colors match in the inspection hole on top. Immediately check the measurement reading in the recess on the comparator reed. Mid-values can be estimated.

8. After use, rinse out both measuring glasses thoroughly and seal them.

Please note that the reagents can also be used for photometric evaluation with photometers PF-12, PF-12Plus, and PF-3. However, the method cannot be applied to the analysis of sea water.

For any safety information, please refer to the hazard warning on the box label and consult the safety data sheet (SDS) which can be downloaded from www.mn-net.com/SDS.
